The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the forecast for Jaconé.

Alright, so the first thing I gotta tell you is that the start of this run is a bit of a let-down. Don’t get your hopes up for the first few days. We’ve got a bit of a flat patch to get through. It picks up for a short window mid-week, but the real story here is the swell that builds towards the end of next week and into the final weekend. That's the one you want to circle on the calendar.

For Jaconé, we’re starting off this Saturday afternoon, August 15th, with a decent 8ft swell from the SSE, but it’s wrapping in real fat and the wind is a messy cross-off at 15 mph. The energy is strong (1867), but the report is calling it marginal. Sunday the 16th is a bit cleaner with an offshore breeze in the morning and a 5ft S swell, but again, the scores are low. Monday the 17th morning is offshore and clean with a small 3ft S swell, but it’s not big enough to get excited about. The water temp is sitting at 73°, which is about a degree and a half warmer than usual for this time of year, so it’s a touch on the warm side, but nothing wild.

Then we hit a dry spell. From Tuesday the 18th through to Thursday the 20th, the swell drops right off. We’re talking knee-high dribble with energy readings dropping into double digits. Thursday morning the 20th is glassy, dead calm, but the swell is only 2ft. It’s a good time for a paddleboard or a swim.

Friday the 21st sees a little pulse of energy again in the morning with a 6ft ENE swell and clean offshore wind, but it’s a short period windswell (7 seconds) and the energy is moderate (430). It’s a tease.

Now, here’s where it gets interesting. After a few more days of junk, we get the real deal. Sunday the 23rd of August morning is when things start to fire. A clean, cross-off wind (5 mph) and a solid 7ft SSW groundswell pumping in with a 12-second period. The energy jumps to 1228. This is excellent for experienced surfers. The water is still warm, wind is light, and it’s set up for a proper session.

But the standout, the one you’re gonna want to plan for, is Monday the 24th of August. The morning is looking strong, but the Monday afternoon is the pick of the entire forecast. We’ve got an 8ft S swell, a very long 14-second period, and offshore wind from the ENE at only 3 mph. The energy is a massive 3045, and the conditions are rated excellent for experienced surfers. This is a solid, powerful groundswell with clean conditions. For a beach break, that long period could make it a bit straight, but with that size and that wind, it’s going to be a heavy, memorable day. This is for the crew who know what they're doing.

Tuesday the 25th stays big but the wind gets messy in the morning. The afternoon cleans up again with offshore wind and a 8ft SSW swell. Wednesday the 26th is another incredible morning with glassy conditions and a 7ft S swell. The energy stays high and the conditions are perfect. The run continues into Thursday the 27th afternoon with another 8ft S swell and clean cross-off wind. It's a solid week of XL surf.

After that, the size backs off into the final weekend. Saturday the 29th and Sunday the 30th are small and wonky with onshore winds. The party is over.

So, the best bet? Monday 24th afternoon. That’s your day. The swell is pumping, the wind is offshore, and it’s a total standout. Get on it if you can handle the size.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
